upgrading cpu of DELL XPS L502x i3 2310M to i7-2860QM

[kspannu]

Hi everyone I want to upgrade my Delll XPS L502x from i3-2310M. my chipset is HM67 and motherboard model is dell "0YR8NN". I have seen many posts where i7-2670QM is installed on  "0YR8NN" motherboard but I could not find motherboard model for i7-2860QM. Can anyone suggest should I go with i7-2670QM or i7-2860QM.

Welcome to the Dell Community @kspannu 

You can use both.

The "TDP" for both is the same and would run a little hotter.

The question is the price and availability???

Do you have Discrete "nVIDIA" or just Integrated "Intel" video???

I have successfully upgraded laptop with i7-2860QM and replaced my HDD with SATA SSD. It is working really good now.

Hi @kspannu , I did the same thing but unsuccessfully. black screen right after turning the laptop on. I put the old cpu back and it works just fine. Could you please tell me which version of bios are you using and firmware in case you upgraded it?

thanks

The latest BIOS for the system is a good idea before trying the CPU upgrade:

That said, this is an aging system with aging voltage regulators on the system board.  The CPU you're installing draws 30% more power than the i3 you had.  A marginal voltage regulator could be at fault here as well.

  @ejn63 unfortunately I already have a 26xx processor installed. The power required is pretty much the same

[ejn63]

It's not, though - the i3 is a 35W CPU -- the i7 is 45W, or almost 30% more power-intensive.

@ejn63 please note that as per reply of person from DELL , L502x has been fully tested for quad core 45W processors. Dell even sold units of L502x with quad core processors. So i don't think that is a problem area.
